Setting the PIRQ to 0 before reading the data produces a short clock pulse.
Moving the write to after reading the data fixes the issue.

The RTEMS_MILLISECONDS_TO_TICKS() macro doesn't round up. Do not use it
to calculate the program timeout in ticks. Check program done condition
after the timeout check to account for pre-emptions.

This I2C driver framework has some major differences compared to libi2c.
* It is compatible to the Linux I2C user-space API.
* It uses generic IMFS nodes and thus reduces the levels of indirection.
* The drivers don't have to mess around with minor numbers to get their
state information.
* No arbitrary bus controller model is assumed. The main task of an I2C
bus controller driver is to process I2C messages. How this is done is
private to the driver.
* Scatter/gather operations are supported (I2C_M_NOSTART).
